Houses with number 13 sell for much less than other properties, a new report has found.

Superstition is a key factor when buying properties, with door number 13 being a whopping €4,355 cheaper than the average Irish property price.

This could benefit house hunters who don’t believe in the unlucky number 13, Martin Clancy of Daft.ie said.

“Our research shows that properties at number 13 are 1.8% cheaper than the average Irish property, which could provide a saving to savvy house hunters with no superstitions,” he said.

Friday the 13th has occurred 13 times since January 2010 and there are 10% fewer transactions on those Fridays.

“What’s interesting about this research is that our superstitions appear to affect not only prices - with properties numbered 13 cheaper than the average - but also quantities, with fewer transactions on a Friday the 13th than on other Fridays,” Ronan Lyons, author of the report said.
